A '''script''' is code written in the language of an interpreter such as [Tcl].


** See Also **

   [scriptSplit]:   split a script into its constituent commands

   [parsetcl]:   

   [scripted list]:   use a script as a list


** Description **

In [Tcl], a script is a collection of 0 or more Tcl commands separated by
semicolon or newline.  Said commands can later be [source]d if stored in a
file, run from a command line invocation of a TCL interpreter, `[[[eval]]`'ed
from a variable, invoked as a part of a call-back, and possibly executed in
other ways.  A script often provides a [library] for use by other scripts.

A script can be created dynamically, and then evaluated using [[`[eval]`].

Scripts can also contain (or generate) code in another language, i.e. [SQL],
[Perl], [ksh], [awk], or even [C], which can then be handed off to to some
other interpreter for evaluation.  [SQL] is probably the most well-known
example of this.  When dynamically generating scripts for another language, it
is necessary to be aware of possible [Injection Attack%|%injection attacks].
